hair algae

For the last month or two I’ve been having a constant battle with brown hair algae. I’ve reduced feedings, kept lights on for only 4-5 hours, dosed my supplements only 2-3 times a week (before I did it once every day) and picked as much as I can every water change but still, it’ll pop up after...

At the beginning of this month I moved back to my parent’s house after a breakup. Before the move I had pretty much no algae in my tank but about a week afterwards I started getting brown hair algae all over my rocks and now it’s getting out of hand. Nitrates and phosphates are both at 0 and I...

not sure if this is a hair algae. It seems to have leaves rather than just hairy. Also the second one is clear and just floats and moves with the current so it’s definitely not an animal or critter. But what is it? Any ideas? Thank you!

Hello, everyone, I've been battling hair algae for a few months and am considering getting a sea hare to tackle the short-term problem. I have a Red Sea 350, and my sump is already quite full with a Reefmat, UV sterilizer, skimmer, and pump. I would like to set up a refugium with Chaeto, but I'm...

Hello reefing community, My parameters are: Nitrates 8.5 Phosphates .01/.02 Alk 8 Mg 1450 Calcium 440 I have some few hair algae. My corals look like if they are starving. My question is. Should i get my phosphates higher?

I’m looking into doing a 3 day black out to try and help with hair algae. I have corals and 1 anemone in the tank. Does blackout mean all lights off for 3 days or just on a low setting?

Any advice as I feel like I’m fighting a loosing battle…. As you can see from the pictures I have a pretty bad GHA problem. It has been like this for a few months now (maybe longer) I’m picking out clumps weekly but it just keeps growing back, most of it is to small to grab with my fingers and...

I have a 13.5 fluvial tank that’s been running for 5 months-ish and I’ve always had hair algae issues with this tank. I keep the water a bit dirty on purpose since it’s my LPS and softies tank. What’s the best invertebrates or fish to get rid of the hair algae? I’ve tried getting rid of it by...

I've been struggling with dino an hair algae for about a year. Sometimes it looks like it's getting better then it just blows up. I've used both vibrant and dosing peroxide on my old 40 gallon... the problem I'm having is on my 150 gallon acrylic aquarium. Would peroxide be a good option? I've...

Hello, I have had this tank set up since October 2023 and it’s always been very “green”. Here are some pics of how it looked along the way; very nasty! As much as I tried to clean it the algae always grew back overnight! The hair algae on the top is getting shorter but there is now very short...

I’ve only had these Zoas for about two weeks I’d say and I noticed two days ago that there is a hair-like thing growing out of two of them. We bought 3 frags and only 2 are affected. The two affected are right by each other (view video) and the other frag is on the opposite side of the tank. I...

I’m thinking this is just green hair algae and some diatoms, but just figured I’d check with some people who are more experienced. I also have hydroids which appeared two days ago. Any concern with them? I was told they would go away on their own?

Its neon green...

What type of algae is this? I need to fix it.

Been battling this hair algae for a couple months now, not sure which kind of algae it is. Bought a bunch of snails and hermits they won’t touch it, got a tomini tang, it won’t touch it. I was getting ready to get a couple emerald crabs but I don’t want to keep adding livestock if they’re not...

I have been dealing with this brown hair algae for the longest time. I've even restarted my whole tank and its back! I currently have a small court jester goby, tuxedo urchin, skunk cleaner shrimp and about ten turbo snails and it seems there is no progress. I do weekly 15% water changes and...

Hi all! I have an issue with my reef tank. It's a 20-gal mixed reef with anemones. So in mid-July, all of a sudden, my anemones started splitting and moving around the tank. It's not the first time my anemones split but it was the first time they moved so much. In a few days, 3 of them died. I...

Hey everyone! I was wondering if anyone could help me with identifying what kind of algae this is? I was wondering if it’s hair or turf algae maybe something else? My tank I still new only two months old now

Looking to add a rock flower anemone and a maxi mini carpet, but have been dealing with a brown hair algae outbreak for about a month. It seems to be slowing down and looks to be thinning out on the rocks. Just wondering if the Algae would stress/ cause harm to the anemone's if added. Thanks

My substrate was filled with GHA, so i took the superficial part out and washed it with hydrogen peroxide I know that kills good bacteria too, but nothing else was working Anyways, when i put it back into the tank, a bit of the algae that stayed got buried Is that a problem? Will it die and...

I have a green hair algae problem meaning i have to constantly brush them off. Before my clownfish was fine with it. today he decided to attack whatever i tried cleaning the algae with. how am i supposed to do the maintenance if he doesn’t let me?? does anyone have any tips????

My tank is getting infested with bubble algae!! Seen a few on the pumps and I regret not cleaning it immediately! Now it’s taking over my rocks. I tried scrapping it off but it’s more difficult then I thought it would be. I dose 2x of reflux and did absolutely nothing to the bubble algae...
